Errata

While we strive to create a perfect resource, not even multiple error checks catch everything. Generating 1000+ pages of new material, it’s impossible to catch everything. What follows is a list of typos that I am aware of in either the Tussy IRB / Workbooks or in various editions of the Algebra Activities IRB / Workbooks. If you know of a typo that is not on this list, please let me know and I will make sure it is corrected in the next edition.

Tussy IRB / Workbooks (copyright 2010)

Page 2-35, Q7: Total sales should be $168,000. [This should also be corrected in the solution on p. 2-53.]

Algebra Activities IRB / Workbooks (copyright 2011)

FACT-10 In “Now you try these!” There should be a +2 instead of a -2 in the algorithm for #1. There should also be some restructuring of the solutions to account for the algorithms in the problems, view the fixed solutions here.

FACT-11 In “Now you try these!” There should be a minus in the algorithm instead of a plus in #1. The answer is fine.

FACT-13 In Example 2, in steps 5 and 6 the signs need to be corrected. The corrected text will look like this.

FACT-14 “The first one has been done for you.” In fact, it hasn’t. But it will be in future editions. 🙂

FACT-40 The 3rd bulleted example should begin with 5x3 instead of 5x2.
